Answer:
- Infinitely many solutions
Step-by-step explanation:
- 3(x + 10) + 6 = 3(x + 12)
- 3x + 30 + 6 = 3x + 36
- 3x - 3x = 36 - 36
- 0 = 0
This equation has infinitely many solutions as for any value of x we have same result
Answer:
it blury put a better one pls
Step-by-step explanation:
X=-14
do you want an explanation <span />
1. Let x be the original amount of baseball cards,
2. half of x was lost so x divided by 2.
3. you buy 18 cards to replace some that were lost
4. You can find the awnser by subtracting 18 from 30, which is 12.
5. Now lets remember that half of your cards were lost. meaning that 12 is only half of what you started with.
6. 12 times 2 would be 24.
7. The Awnser is 24
8. To check your work, you can say x=24, 24 divided by 2 is 12, and 12 plus 18 is 30.
